Android Studio: Enter key won't create new line where block will [duplicate]

In Android Studio, my cursor is white rectangle. I'm cannot write anything. And changed my keyboard button actions.
h-->left arrow j-->down arrow k--> up arrow l-->right arrow
How can I fix problem or can I reset Android Studio settings?

Just got the same problem as yours. And this is the solution:
Go to File > Settings > Editor > General > Appearance, then uncheck the Use block caret

Try fn + ins. That worked for me.

Go to settings and plugins and just disable the IdeaVim plugin it works in 2020.itx also occurs due to this extension.

In windows, win+insert worked for me.

Presse Fn+0. It will work instantly.

go to plugins and disable IdeaVim then restart android studio it will be ok ...

Press Fn + Del on your keyboard together.
Explanation: Its because Delete key on keyboard has Insert function. So pressing Del along with Fn key will enable Insert mode within your editor from Overwrite mode as in your case.

It's ins in the latest version of Android Studio.

In windows if you press INSERT key cursor mode will get change,use WINDOWS + INSERT to get back into normal mode

For mac users just right click and deselect "Column selection mode" or press Shift + Command + 8

Just restart Android Studio and voilà !
None of the other solutions worked for me (Windows 7, maybe with an inactive Lock Num key).

Android Studio import class shortcut

I've looked at How to auto import the necessary classes in Android Studio with shortcut? but it doesn't help.
Ctrl+Alt+O does nothing.
When I press alt+enter I get the following:
I do not want this, I wish for it to appear as a normal import at the top of the file.
What are these shortcuts called in Android Studio? This program makes it complicated to edit such simple shortcuts.
I also have auto-imports, but it isn't working:

Finally after hours of trail and error the following settings is what fixed it:

Pressing Ctrl + Space on Mac will open a dialog to choose which library to import.

or
goto file -> setting select keymap and search for auto import and add keyboard short cut

Ctrl + Space Not Working Properly Android Studio

i am facing problem in android studio. In eclipse when i want to use class like Intent, then i write intent starting with lower case it give me suggestion box indicating class name Intent, but in android studio if i type intent starting with lower case it does not Provide Suggestion class name Intent.Thanks in advance.

In my case Ctrl + Space was overloaded by mac shortcuts. And even in the case, I disabled them, they conflict with Android Studio.
So, I gave them another keys and it solved the problem.
Go to the System Preferences -> Keyboard -> Shortcuts -> Input Sources and use new keys for them.

The problem is that Android Studio has different key binding than Eclipse, but you can set the key binding to be the same as in eclipse in android studio settings. Also by default ctrl + space is case sensitive in Android studio, you need to turn that off too.
Move to File -> Settings -> Keymap and change keymaps settings to eclipse so that you can use the short cut keys like in eclipse.
You can set 'Case sensitive completion' to 'None' in IDE Settings > Editor > Code Completion.
That should do it :)

File --> Settings --> Editor --> General --> Code Completion --> Case sensitive completion --> None

android studio ctrl + space opens documentation window

I have updated my Android Studio to the newest version, but now when I call the auto-completion/suggestions with CTRL+SPACE the suggestion box opens but the documentation window opens as well.
Has anyone experienced this and know how to disable the opening of the documentation window?

I'm using Android Studio 0.8.1 on OSX and have been experiencing the same irritating behavior.
The answer by #daniel-gabriel was not was I was looking for.
A better solution seems to be to go to Preferences > IDE Settings section > Editor > Code Completion (in AS 1.2.2 located in Preferences->Editor->General) and unticking the option Autopopup documentation in (ms):

Ctrl-Q toggles between doc window states (when using the default keymap).
Possible states are:
-Hidden
-Shown to the side of the auto-complete list
-Docked as one of the tabs
If you have a different keymap, you can search for this action in Settings -> Keymap. The action is called "Quick Doc".

For ubuntu 14.04 :
File > Settings > Editor > General > Code Completion
And unticking Autopopup Documentation will hide it.

For Windwos && Linux (ubuntu) :
File > Settings > Editor > General > Code Completion
For Mac :
Android Studio > Preferences > Editor > General > Code Completion
1. unChecked : AutoPopup documentation (in CodeCompletion)
2. unChecked : AutoPopup (in Parameter Info)

On Mac OSX, to restore the Documentation window to an auto-hide popup, toggle the popup window toolbar to checked state, from the popup windows gear icon, and then click "Restore Popup" icon in the documentation window toolbar.

I prefer the quicker solutions...
Press Ctrl + Space and let the "Documentation" window pop-up.
1) Click on the Settings icon and uncheck all the options except "Docked Mode".
2) Now push documentation window to the right, so as to make it invisible.
With this even though with press of "Ctrl + Space", internally command will pass
to open the Documentation Window but it will not be visible and interfere with the
workspace.
I hope that helps. Happy Coding...

Android Add PinIt Button using Pinterest Jar NoClassDefFoundError

I am trying to add the Pinit button to my Android App. I have downloaded the SDK and copied the pinit-sdk-1.0.Jar into my Project/libs folder. I'm even able to make the necessary PinItButton import to my code. But for whatever reason, my XML isn't finding the Button widget, and so I tried to add it just using Java with this code:
LinearLayout ll = (LinearLayout)findViewById(R.id.pinterest_layout);
PinItButton pinit = new PinItButton(this);
ll.addView(pinit);
I know this is the correct way to add something using code because I tested it by adding a generic Button first. I run my project then, and it crashes on the line where I set up the PinItButton. This is the error that my logcat spat back at me:
07-22 01:19:52.160: E/AndroidRuntime(32367): java.lang.NoClassDefFoundError: com.pinterest.pinit.PinItButton
I believe that I'm understand what it is telling me, but what else should I be attempting then to create the PinIt button? Any help would be great. Thank you!

It was #Kai who helped me figure out my problem. I needed to check my libraries. I did that by going to project --> Properties --> Java Build Path --> Order and Export tab, then checking the library and clicking OK. My problem was then solved!
